Figure 1. Mann-Whitney analysis of normalized miR-15b-5p expression in tumor tissues between HNSCC patients with short and long time of LRC (A); Receiver operating characteristic (ROC) curve of the normalized miR-15b-5p expression to detect HNSCC patients with short time on LRC (B); and Kaplan–Meier curves of locoregional relapse-free survival for HNSCC patients with low and high expression of tumor tissue miR-15b-5p (C). LRC: Locoregional control; AUC: area under the curve.
